Exterior Window Cleaning Guide for Homeowners
What professional exterior window cleaning includes, and why it beats the streaky DIY result.
Professional exterior window cleaning removes dirt, pollen, road film, and buildup from glass and window frames. Osborne Pro Wash uses a water-fed pole system: deionized water pumped up a telescopic pole to a soft brush. The brush does the scrubbing, the purified water rinses, and because the minerals are filtered out, it dries without spots. No squeegee, no towel drying, and no ladders against your home.
What's included in exterior window cleaning:
Service Includes
- Exterior glass on all accessible windows
- Window frames cleaned along with the glass
- Second and third story windows reached from the ground
- Deionized water rinse that dries spot free
Why It Builds Up
- Pollen and dust
- Rain spotting
- Sprinkler overspray
- Road film near busy streets
One honest note: glass that has already been etched by years of sprinkler overspray or hard water may not come fully clear. Pure water and a soft brush lift what is sitting on the surface, not damage that has gone into it.
How Often Should Exterior Windows Be Cleaned?
Most homes benefit from exterior window cleaning once or twice a year. Homes near busy roads, with lawn sprinklers that hit the windows, or surrounded by trees often need cleaning closer to twice a year to stay ahead of buildup.
DIY vs. Professional Window Cleaning
DIY window cleaning with a spray bottle and paper towels usually ends in streaks, because tap water leaves its minerals behind as it dries. That is what the spots are. A water-fed pole system filters those minerals out first, so the water dries clean on its own. It also reaches second and third story glass from the ground, which is where most DIY attempts either stop or turn into a ladder nobody should be on.
Why Hire a Professional
Osborne Pro Wash is owner-operated and based in Morrow, Ohio, serving Morrow, Maineville, Mason, Loveland, Lebanon, Kings Mills, Landen, and South Lebanon. Exterior Window Cleaning is offered as an add-on to a house wash rather than on its own, since the house wash already handles everything else on the exterior and both get done in the same visit.

Window Cleaning FAQ
Do you clean window screens too?
No. We ask that you remove your screens before service so the brush can reach the full pane. Screens left in place block the glass behind them.
Can you clean second and third-story windows?
Yes, up to three stories, all from the ground. The pole system means no ladder leaning against your siding or standing in your landscaping.
How long does window cleaning take?
Time depends on the number of windows and home size, but most residential jobs are completed in a single visit.
Should I bundle window cleaning with house washing?
Exterior Window Cleaning is only offered as an add-on to a house wash, so it is always the same visit. Your windows already get sprayed and rinsed during the house wash. The add-on is what takes them from rinsed to spot free.
